Thanks so much Larry. I thought that was it but unit looked newer, so I questioned. Appreciate prompt response

As Larry said correctly, the 30th week of 1997. Couple of good web sites for dating HVAC and HW heaters.

Hey Jeffrey, welcome. Thanks for your response, but I didn’t see where you listed the actual web sites. I found a couple, but didn’t find anywith this brand.
